Genetic Differentiation of Chinese Fir Populations From Mainland China and Taiwan as Revealed by Genotyping‐By‐Sequencing Analysis, With Implication for Taxonomic Position of the Species

open access: yesEcology and Evolution, Volume 15, Issue 4, April 2025.
This study investigates the genetic diversity and taxonomic status of Cunninghamia lanceolata and Cunninghamia konishii, exploring their differentiation due to climate change and glacial isolation. Genotyping‐by‐sequencing (GBS) analysis of 92 accessions revealed minimal genetic differentiation and significant gene flow from mainland China to Taiwan ...

Permian phytogeography and climate [PDF]

open access: yesThe Paleontological Society Special Publications, 1992
A greater number of floral provinces have been defined for the Permian than for any other Phanerozoic period, and this is presumably the reflection of a well differentiated set of climate zones. These floras have been assigned to an idealized set of ten “biomes” as defined on the basis of the equator-to-pole spectrum of present day climates (Ziegler ...
